To all 'whom t may concern:

Be it known that I, AINswon'rH BUCK, a citizen of the` United States, residin in Summit, in the county of Union and tate of New Jersey, have made certain new and useful improvements in VVindow-Cleaners Safety a specification.

The invention relatesto window cleaners safety devices and especially to the clamp or means for attaching said devices directly to some structural member of the window or building.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized Vand attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and constituting a part hereof, illus` trate one embodiment of the invention,` and together with the description, serve to ex plain the principles of the invention.

0f the drawings Fig. l is a perspective view of a window showing the clamp` of the safety device attached to the window mullion;

Fig. 2 is an enlarged horizontal section, taken on the line 2 2 of Fig. l, and show ing the clamp locked on the mullion;

Fig. 3 is fragmentary, side elevation, greatly enlarged, looking at the clamp and mullion of Fig. l from the right and at Fig. 2 from the botto-m of the ligure;

Fig. 4 is a view co-rresponding to Fig. 2, but showing the clamp unlocked .from the mullion; and V Fig. 5 is a view corresponding to Fig. 3, but, like Fig. 4, showing the clamp unlocked from the mullion.

The invention provides a clamp or like attaching means for a window cleaners safety device which is practically instantly attachable directly to a mullion, or other part of the window or building structure, which firmly and automatically locks in such clamped position and which remains so locked until manually released. Other features and advantages of the invention will be set forth in connection with the fol- Devices, of whichthe following is lowing detail description of the present pren ferred embodiment.

Referring now to the accompanying drawings, illustrating by way of example one embodiment of the invention, the safety clamp or attaching device'is especially designed to engage and hold itself firmly or iixedly` in place against vertical displacement, as well as against horizontaldisplacement. The clamp is shown in Fig. l fixed in position on the vertically disposed mullion 'of a vertically hinged window, the clamp or safety device being attachable to the mullion at any desired height, the clamping means automatically locking during the clamping action and firmly and fiXedly holding the device in position until the locking means is manually released. It will be understood that the application of the clamp to the mullion and to the particular form ofwindow shown is illustrative and explanatory and is not restrictive of the invention.

In the embodied form and according to one feature of the invention, the clamp engages four sides of the mullion or other or corresponding structural part of the win i dow or building. As embodied, the clamp is pro-vided with a lip or flange l, adapted to take around or about the face 2 of the `mullion 3, and to prevent sidewise or horizontal displacement of the clamp. What may conveniently be termed the back 5 of the clamp fits aboutthe next adj aoent face 6 of the mullion. If desired, a layer of leather or other suitable material 7 may be fitted within the end 5 to form a bearing i surface for the mullion which will `avoid scratching or marring it; and which will constitute a resilient pressure surface to in crease the clamping pressure of the clamp on the mullion.

' The third sid-e 8 of the clamp encloses or embraces the* corresponding side 9 of the mullion, and is provided with a shoulder l0, which provides for cases where the mul lion, or other supporting part or member, has a bead ll projecting laterally or sidewise from its front face, as shownin Figs. and 4l. The fourth side 12 of the clamp preferably extends only partially across the 'fourth side 14: of the mullion or other supporting member. In the lembodied form the clamping mechanism or holding device and the locking means are mounted or located upon this fourth side.

As embodied, to provide a suitable mountins er eePPert fer Seid @lecturing deriee elle said lo'ekingdeyicd :t'lieuolamp frame or body Y is provided with a member or p`art15, projecting outwardly longitudinally from the side l2 of the clamp body, yand preferably vsubstantially perpendicularly thereto, The
